CI fix: app_api is now bundled app from NC 30.0.1 (#303)

Since Nextcloud 30.0.1 version, AppAPI has become built into the server,
so now the `stable29` branch is the branch for Nextcloud `28` and `29`,
and the `main` branch corresponds to the `master` branch of the server,
and branch 30 is there for Nextcloud `30.0.1+`

It is tough..
